The biggest uncertainty was in the Democrat-led Assembly, where members have shared the concerns of the teachers' union and other school groups. But Assembly members appeared resigned Friday to include it in hopes of getting a on-time budget Sunday.

"I think it’s important to my constituents that it be made permanent. However, there are a couple of exceptions that we’d like to see written into it," Assemblywoman Donna Lupardo, D-Endwell, Broome County, said Thursday.

What's included?

There have been some discussions among lawmakers about adding a few exceptions to the cap in the final agreement.

One would allow school districts to exempt BOCES capital costs from counting against the cap, a move that would allow them to collect additional tax without exceeding the cap.

The other would count payment-in-lieu-of-tax agreements — a tool used by economic-development agencies in hopes of spurring construction — as part of a county or municipality’s tax base, which would push their total allowable tax levy higher under the cap.

Both tweaks date back to 2015, when Cuomo and lawmakers agreed to allow the state Department of Taxation and Finance to make them happen through regulations.

But the department never approved the regulations, and when lawmakers passed a new bill in 2017, he vetoed it, arguing that they would erode the tax cap.

And Heastie said Friday, "You've got to read the bill" when asked if any of them would be included.

A few exemptions already exist to the cap, such as soaring pension costs or other tax growth in a community.

Assemblywoman Sandra Galef, an Ossining Democrat who chairs her chamber’s Real Property Taxation Committee, said she supports the permanent extension of the tax cap because lawmakers can make changes to it in the future, anyway.

“If there’s something that is really going on where the tax cap is really hurting communities, then I think we have to come back and revisit other kinds of exemptions to it,” she said.

“I’m sure the governor thinks it’s solid, it’s forever. But I don’t view it that way because we can always change anything we do.”
